419ef3b7cc CNetAddr: fix IsRFC2544 comment (Mark Tyneway)

Pull request description:

  The comment describing the functionality of `CNetAddr::IsRFC2544` is incorrect.

  46d6930f8c/src/netaddress.h (L57)

  It should actually read `198.18.0.0/15` based on [RFC 3330](https://tools.ietf.org/html/rfc3330):

  ```
     198.18.0.0/15 - This block has been allocated for use in benchmark
     tests of network interconnect devices.  Its use is documented in
     [RFC2544].
  ```

  See [RFC 2544](https://tools.ietf.org/html/rfc2544) here.

  See the implementation here:

  47d981e827/src/netaddress.cpp (L142-L145)

  This PR also adds tests for the minimum and maximum values that are valid RFC 2544 addresses.
